Give and Take
Source Institutions
In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.
Matter of Degree
Source Institutions
In two separate bags, learners mix water with Epsom salts and detergent.
Liquid Crystals Interact with Light!
Source Institutions
In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.
Taking Its Temperature
Source Institutions
In this activity (pages 5-7), learners investigate the properties of smart materials, which are materials that respond to things that happen around them.
Geyser
Source Institutions
This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.
Weather Stations: Winds
Source Institutions
In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.
Curie Point
Source Institutions
In this activity best suited as a demonstration, learners observe that when a piece of iron gets too hot, it loses its ability to be magnetized.
Changing the Density of a Liquid: Heating and Cooling
Source Institutions
Learners investigate how the temperature of water affects its density.
Temperature Affects Dissolving
Source Institutions
Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.
What is a "Model"?
Source Institutions
In this activity, learners simulate the behavior of the atmosphere.
Turning the Air Upside Down: Spinning Snakes
Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.
